Abstract: Techniques for modifying an imaging cartridge includes providing the imaging cartridge comprising a body including a circuit holding structure sized to hold an electronic circuit and forming a modified circuit holding structure, with the modified circuit holding structure sized to hold a replacement electronic circuit. At least one dimension of the replacement electronic circuit may be greater than a corresponding dimension of the electronic circuit.

Abstract: An electrical power probe is provided. In one aspect, an electrical power probe includes a power probe control unit adapted to connect to a direct current (DC) power source and receive an input source voltage from the DC power source. The power probe control unit comprises a power switch controlling the switching of the input source voltage to a cable. A power probe wand includes a conductive wand tip and a user controlled switch, with the wand tip being connected to the power switch by the cable. The power probe control unit sends a query message to the power probe wand. The power probe wand unit sends a response to the power probe control unit in response to the query message, with response indicating the position of the user controlled switch. The power probe control unit selectably switches the power switch based on the position of the user controlled switch.

Abstract: A davit arm system includes a base that supports a davit arm and engages an underlying ground surface. The system components are preferably designed for arrangement in alternative ways to accommodate different installation environments, and/or for packaging in a bag that may be carried by a single person. The relative positions of the components are preferably adjustable relative to the base to further accommodate different applications. Yet another desirable option is to mount the davit arm on the support base in a manner that allows rotation about both a vertical axis and a horizontal axis. A winch is preferably mounted on the davit arm in a manner that counterbalances the davit arm relative to its vertical axis of rotation.

Abstract: A buckle includes a first assembly and a second assembly which are selectively latched to one another. Each assembly includes a keeper and a latch secured between a pair of first and second outer plates. The two assemblies are identical in construction and configured to selectively interlock in a manner that provides a reliable buckle.

Abstract: A descender includes a frame having opposing first and second plates which define a gap therebetween. Three bearing members are movably interconnected between the plates and linked to an operator. A flexible member has opposite end portions which extend in opposite directions, and an intermediate portion which is routed about the bearing members in a manner which forms a knot. Movement of the operator relative to the frame causes the bearing members to move relative to the frame and thereby loosens or tightens the knotted, intermediate portion of the flexible member about the bearing members.

Abstract: A first roof mounting assembly includes first and second brackets which are disposed on top of a roof and fastened to adjacent beams which support the roof. First and second brackets are mounted to respective brackets and interconnected together with an anchorage. A second roof mounting assembly includes first and second brackets having base members and intermediate members. The base members are connected to the roof beams, and the intermediate members are interconnected by a cross-member which supports the anchorage. In a preferred application, the anchorage accommodates passage of a slotted coupling device movably mounted on the safety line, and the safety line may be secured to the anchorage without obtaining access to either end of the line.

Abstract: A protection apparatus aids a user of the apparatus in defending against an attacker and signals that the user is being attacked. The protection apparatus attaches a spray retardant and an alerting device to the user of the apparatus and includes a trigger mechanism that activates both the spray retardant and the alerting device substantially simultaneously. The trigger mechanism is capable of being activated by a single digit of a hand of the user.
